Hi, English isn’t my mother tongue so I was asking myself that question since I first encounted a w/… Back then I was like: “What tf does ‘w slash’ stand for?” And when I found out I was like “How, why, and is it any intuitive?” But I never dared to ask that until now
Hx, Rx, Tx are history, prescription and treatment in medical jargon
Dx too
Dx nxts
Sx for symptoms also
sx makes me think of something else than symptoms
That sounds like a Sx of something
